Description
Technical field
The present invention relates to a kind of reaction kettle of the esterification, belong to chemical industry equipment.
Background technology
Chemical industry is used a large amount of reactors.The structures such as the heating of reactor, cooling general employing chuck, coil pipe, heat transfer structure is all generally independent use.This independent heat transfer structure can meet the Chemical Manufacture requirement of overwhelming majority part.But because heat transfer structure is single, often conduct heat slow, add thermal material and cooling material time long, and the production of the production of chemical products, particularly fine chemicals often adopts the step mode of production, this heat transfer structure causes production efficiency low, and utilization rate of equipment and installations is not high.Esterification particularly, reaction temperature is generally higher, and material is warming up to reaction temperature by room temperature, by reaction temperature be cooled to can discharging temperature, expended the plenty of time, these times are consuming time 2～3 times of reaction temperature often, had a strong impact on production efficiency.
Summary of the invention
The objective of the invention is to disclose a kind of reactor, it has intensification, the fast characteristics of lowering the temperature, and for the production of chemical products, can save a large amount of intensifications, temperature fall time, has improved production efficiency, and utilization rate of equipment and installations also improves greatly.Reactor of the present invention is more suitable for being applied to esterification.
Technical scheme of the present invention is:
Reaction kettle of the esterification, comprise that kettle, agitating device and heat transfer unit (HTU) form; Heat transfer unit (HTU) adopts chuck and coil arrangement to combine; Jacket structuredly be divided into two independently parts, go up chuck and lower chuck;
Triple valve is contained in the heat transfer medium inlet of described coil pipe, and the heat transfer medium outlet of coil pipe also contains triple valve, and coil pipe can be by thermal medium and cold medium;
Triple valve is contained in the heat transfer medium inlet of described upper chuck, and the heat transfer medium outlet of upper chuck also contains triple valve, can be by thermal medium and cold medium;
Triple valve is contained in the heat transfer medium inlet of described lower chuck, and the heat transfer medium outlet of lower chuck also contains triple valve, can be by thermal medium and cold medium.
Its principle that can save the heating and cooling time is: coil pipe and lower chuck adopt conduction oil as heat transfer medium, upper chuck adopts water as heat transfer medium, during intensification, the thermal conductance deep fat is entered by the heat transfer medium inlet of coil pipe and the heat transfer medium inlet of lower chuck, heat transfer, to material, heats up just very fast like this; During cooling, cold conduction oil is entered by the heat transfer medium inlet of coil pipe and the heat transfer medium inlet of lower chuck, cooling water from the heat transfer medium inlet of chuck enter, cooling by their associating, greatly reduce cool time of material.
Or coil pipe and upper chuck adopt conduction oil as heat transfer medium, lower chuck adopts water as heat transfer medium, and during intensification, the thermal conductance deep fat is entered by the heat transfer medium inlet of coil pipe and the heat transfer medium inlet of upper chuck, conducts heat to material, heats up so just very fast; During cooling, cold conduction oil is entered by the heat transfer medium inlet of coil pipe and the heat transfer medium inlet of upper chuck, cooling water from the heat transfer medium inlet of chuck enter, cooling by their associating, greatly reduce cool time of material.
Also can adopt coil pipe, upper chuck and lower chuck all to adopt conduction oil as heat transfer medium, during intensification, coil pipe, upper chuck and lower chuck all pass into the thermal conductance deep fat, and during cooling, coil pipe, upper chuck and lower chuck all pass into cold conduction oil; But do not advise so doing, the specific heat of water appearance is larger after all, and cooling effect is better than cold conduction oil, and cost can be ignored.
The good effect that the present invention produces is: reactor of the present invention heats up and lowers the temperature fast, easy control of temperature, adjusting, greatly reduce reaction mass and be warmed up to by room temperature the time that reaction temperature needs, also can greatly reduce material by reaction temperature be cooled to can discharging the needed time of temperature, obviously improved production efficiency, improve the utilization rate of equipment, be specially adapted to the esterification that reaction temperature is higher.
